Title: Diaphragm valve
Inventor: WILLIAMS ROGER D
IPC: F16K7/00
Filed: 1995-08-25
Abstract: A diaphragm valve including a housing forming an open chamber, and inlet and outlet conduits opening into such chamber.          A flexible membrane is mounted in the chamber and operated by a control valve to move the flexible membrane between an open position permitting fluid flow through the valve and a closed position blocking such flow. In some embodiments, the membrane is moved to its open position by exposing the upper surface of the membrane to a negative pressure in the outlet conduit and utilizing atmospheric pressure to close the valve. In other embodiments, a positive pressure is used to close the valve, and atmospheric pressure permits the membrane to move to its open position. In some embodiments, the membrane may be provided with a stiffening member so that it can seat across the opening of the outlet conduit in its closed position. In some embodiments, the inlet and outlet conduits are axially aligned, and in other embodiments they extend in perpendicular relation to one another.

Title: Process for purifying collagenase
Inventor: LEE CATHERINE
IPC: C12R1/145
Filed: 1994-04-13
Abstract: A process for purifying crude collagenase is disclosed. The collagenase purification process includes providing a stabilized crude collagenase solution containing collagenase, pigment, toxins, bacterial materials, and proteolytic enzyme impurities including clostripain, trypsin, and caseinase. The stabilized collagenase solution is applied to hydroxylapatite packing. pigment and caseinase are eluted with a first solution comprising about 0.05 M to about 0.3 M phosphate buffer, and then collagenase, trypsin, and clostripain are eluted with a second solution comprising about 0.35 M to about 0.5 M phosphate buffer to provide a first collected solution. The first collected solution is then applied to gel filtration packing and collagenase and clostripain are eluted with a neutral pH buffer solution, to provide a second collected solution. The second collected solution is then applied to Reactive Red 120-Agarose packing and collagenase is eluted with a neutral pH buffer solution to provide purified collagenase. The process provides extremely pure collagenase in high yield with reduced consumption of eluting solutions and avoids unpredictable gradient eluting techniques.

Title: Mechanical interlock mechanism for switched electrical connector
Inventor: SANDOR JOHN L
IPC: H01R13/625
Filed: 1996-05-13
Abstract: A switched electrical device adapted to be coupled to a complementary locking type electrical connector by initial relative axial movement therebetween and subsequent relative rotational movement therebetween, The switched electrical device includes a housing with an inlet opening for receiving the complementary electrical connector, a rotatable locking type electrical connector with a set of electrical contacts for engaging the electrical contacts of the complementary electrical connector, a switch mounted within the housing for selectively supplying electrical energy to the set of electrical contacts of the electrical connector, an operating handle for moving the switch between "on" and "off" positions, and an interlock mechanism for releasably locking the switch. The interlock mechanism selectively locks the switch in its "on" position so that it cannot move to its "off" position, until after the complementary electrical connector has been inserted into said opening and rotated to a locked position. The interlock mechanism also prevents removal of the complementary electrical connector from the inlet opening until the operating handle has been moved to its "off" position, which disconnects power to the electrical contacts of the switch connector and the electrical contacts of the complementary connector.

Title: Apparatus for Storing a Variable Quantity of Moving Strand Material
Inventor: JOSOF PETER LARRY
IPC: H01B13/02
Filed: 1996-05-16
Abstract: Apparatus 500 for storing a variable quantity of strand material 200 comprises a generally cylindrical drum 110 that stores a layer of elongated strand material around its exterior surface. The layer is formed by wrapping the strand material in adjacent convolutions around the exterior surface which is energized to move in a direction which is parallel to the central axis 101 of the drum. Consequently, the strand material also moves in a direction that is parallel to the central axis. A winder assembly 510 is mounted on a first shaft 140 at an input end of the drum, and includes a strand payout member 511 for depositing strand material onto the drum. The drum is mounted on a second shaft 150 which contains the common support structure of the drum and the equipment for energizing the exterior surface. An unwinder assembly520 is mounted on a third shaft 160 at the output end of the drum, and includes a strand-receiving member 521 for removing the strand material from the drum. The shafts are coaxial with each other and each is capable of independent rotationalmovement. Accordingly, the volume of strand material stored on the drum may be varied by changing the relative rotational speeds and directions of the different shafts. In this manner, the volume of strand material can be varied in order to buffer speed variations along a manufacturing line.

IPC: H01H9/34
Filed: 1995-01-23
Abstract: A circuit breaker (I) comprises a base (20) and cover (21) with rear, front and side wall portions which cooperate on assembly of the base (20) and cover (21) to form an enclosure for the various components of the circuit breaker. An enclosed arc chamber (50) into which arc gases generated on tripping of the breaker under load are exhausted is defined by a longitudinal dividing wall (51), portion of the rear wall (22a, 22b) and a transverse dividing wall (53). The arc gases enter the chamber (50) through an aperture (52) and are prevented from exiting the breaker. This eliminates cross-phasing in the load centre in which the circuit breaker is mounted.

Abstract: A method in electroconvulsive therapy (ECT) to use ictal EEG data for clinical determination of the adequacy of an induced seizure in a patient. The method includes employing  an  ECT device to  apply  electricity to  the patient in an ECT session to induce seizure activity.  The electroencephalographic (EEG) data is detected during the seizure and selected  EEG data  parameters  are derived therefrom.   Next,  the likely adequacy of the  induced seizure is computed by comparing the selected EEG data parameters of the patient to ictal EEG data parameters wherein the  adequacy of the corresponding seizure  or seizures is known,  and the computed likely therapeutic adequacy of the induced seizure is displayed.
Patent CA-2184530-A1 (CA)
Inventor: BETTS WILLIAM LEWIS
IPC: H04L27/34
Filed: 1996-08-30
Abstract: A high speed modem for simultaneously transmitting both voice and precoded digital data signals over a single communication channel.  The modem is operable to combine a voice signal with a precoded digital data signal for transmission at high speeds, high power levels and low distortion previously attainable by high speed data-only modems.  The voice signal is processed using conventional data processing techniques to produce a voice signal and a control signal containing information relating to the coding of the voice signal.  The control signal is multiplexed and mapped for transmission with the digital data.  Selected bits of the multiplexed data are used to define the rotation of the digital data and to rotate the voice vector.  The digital data is precoded to compensate for and minimize noise in the communication channel.  The rotated voice vector and the precoded digital data are then combined and transmitted.  At a remote location, the transmitted signal is received by a receiving modem and is filtered and separated to thus recover the individual coded signals.  The separation of the coded voice signal from the precoded digital data signal is performed prior to reconstruction of the precoded digital data signal.  The coded voice signal is then de-rotated.  The coded voice and precoded digital data signals are then individually decoded to retrieve the voice and data signals that originated at the transmitting modem.
